In the field of photocatalysis, the heterojunction strategy is one of the effective ways to settle the problems of rapid recombination and sluggish mobility of the photo-generated carriers. Herein, we used a strategy of electrophoretic deposition to synthesize Z-scheme CdS/BiVO 4 . Interestingly, compared with the pristine CdS and BiVO 4 , the prepared CdS/BiVO 4 showed effective charge separation, high degradation efficiency and well photocatalytic stability. It demonstrated that electrophoretic deposition can successfully construct photocatalyst steadily and effectively heterostructured CdS/BiVO 4 . Meanwhile, the electron transfer paths between BiVO 4 and CdS were probed by the DFT calculations. We infer that there is a Z-scheme mechanism between BiVO 4 and CdS. Moreover, this efficient strategy can support more applications for more efficient composition design of semiconductor heterojunctions.
